Publisher - Insert a personal bullet

Hello,

I need to insert custom bullet points (not the 5 offered by default). The problem is that in Publisher, I can't find the option. In PowerPoint, no problem, but here... :/

I'm using the 60-day trial version of Publisher 2007, and it tells me that I have access to all the capabilities of the software.

I want to specify that I have already searched the forum :)

Thank you very much in advance
